Seismic Performance Analysis of Non-uniformly Corroded Reinforced Concrete Column Assembly Joints Strengthened with CFRP
In order to analyze the seismic behavior of non uniformly corroded reinforced concrete column assembly joints strengthened with CFRP. In this paper, one corroded and unreinforced RC column specimen and four corroded but CFRP Reinforced RC column specimens were fabricated. According to the hysteretic curve, the skeleton curve change and stiffness degradation of each specimen are analyzed, and the load displacement condition of the assembled joint is judged. According to the strain of the assembled joint of reinforced concrete column, the ductility, energy consumption and other properties of each joint are analyzed, so as to analyze the seismic performance of the specimen. The results show that the unreinforced reinforced concrete column specimens have small ductility, low energy consumption and poor seismic effect; The reinforced concrete column specimens strengthened with CFRP have larger ductility, higher energy consumption and better seismic performance. Conclusion: the seismic performance is related to the stiffness, ductility coefficient, energy dissipation coefficient and other indicators. The larger the above indicators, the better the seismic performance, which plays an important role in improving the stability of the assembly structure.
